Metallic Bonding and the Physical Properties of Metals Chemistry Tutorial
- A metal is a lattice of positive metal 'ions' in a 'sea' of delocalised electrons.
- Metallic bonding refers to the interaction between the delocalised electrons and the metal nuclei.
- The physical properties of metals are the result of the delocalisation of the electrons involved in metallic bonding.
- The physical properties of solid metals are:
⚛ conduct heat
⚛ conduct electricity
⚛ generally high melting points and high boiling points
⚛ malleable (can be hammered or pressed out of shape without breaking)
⚛ ductile (able to be drawn into a wire)
⚛ metallic lustre
⚛ opaque (reflect light)
